non-square nodes, bigger labels?

Goals:

• Make graph labels more legible
• Find optimal layout so labels don't overlap

In research for #53, I'm thinking that with graph autolayout we might want to put the node labels inside the boxes. The algorithms take node w/h into account to come up with the optimal placement.

Though I suppose that the algo could take an external label's size into consideration.

Also, snap-to-grid isn't needed with autolayout on. Should this be a mode to switch: autodesign or snap-to-grid? Or autodesign to rule them all?

Zoomable UI is trumping this.
